High strength and lightweight achieved at low cost through SANJO's development of "screw and diffusion bonding"!
We propose a hollow lightweight manufacturing method for e-Axle motor shafts and rotor shafts primarily used in BEVs (battery electric vehicles). This method involves machining the inner diameter of the shaft to the extreme for weight reduction. Additionally, since it does not use swaging or welding, it is not limited by material selection. 【Features】 ■ High strength/lightweight ■ Low cost ■ No material restrictions ■ Capable of dissimilar material joining ■ Reduced environmental impact in the manufacturing process ■ Does not require advanced technology or skills, making overseas expansion easy *For more details, please refer to the PDF document or feel free to contact us.
